摘要： A plasmon generator includes a first portion and a second portion that are adjacent in a first direction orthogonal to the direction of travel of light propagating through a core. The second portion includes a front end face located in a medium facing surface of a magnetic head. The core has a concave portion recessed from the top surface of the core. At least part of the first portion is received in the concave portion. The concave portion has a surface including an evanescent light generating portion. The first portion includes a plasmon exciting portion opposed to the evanescent light generating portion. The evanescent light generating portion is inclined relative to a first surface.

摘要： A method of manufacturing a thermally-assisted magnetic head includes providing a light source unit including a laser diode; providing a reflection board, and a photo detector; driving the laser diode to emit a light beam towards the reflection board; performing an alignment between the light source unit and the thermally-assisted magnetic recording head section, based on a reflected light of the light beam reflected by the reflection board, then passed through the optical waveguide and finally detected by the photo detector obtaining the maximum power in a LED emission state of the laser diode; and bonding the light source unit to the slider after the alignment is completed. It improves alignment accuracy between a light source unit and a slider during a bonding process therebetween, prevents a laser diode of the light source unit instability, and improves performance of the thermally-assisted magnetic head finally.
